The perfect one step solution for creating Ice/Sliding Mazes in both Reign of Chaos and The Frozen Throne. It is the only decent system around and it even works in RoC, is lagfree, perfectly optimized, fast and reliable. The included TerrainKill feature frees you from the tedious task of creating a thousand kill-regions.
